Brief Description

Mytob.OW is a worm that spreads by copying itself, without infecting other files.

It affects productivity, preventing tasks from being carried out:

In the affected computer:
it converts the computer into a platform for taking malicious action surreptitiously: spam sending, launch of Denial of Service attacks, malware distribution, etc.

It reduces the security level of the computer:
it terminates processes belonging to security tools, such as antivirus programs and firewalls, leaving the computer defenseless against attacks from other malware; it awaits remote-control orders received through
IRC or FTP.

It uses stealth techniques to avoid being detected by the user:

It terminates processes corresponding to several security tools, such as antivirus programs and firewalls, to prevent detection.

It deletes the original file from which it was run once it is installed on the computer.

Mytob.OW uses the following propagation or distribution methods:

Exploiting vulnerabilities with the intervention of the user: exploiting vulnerabilities in file formats or applications. To exploit them successfully it needs the intervention of the user: opening files, viewing malicious web pages, reading emails, etc.

Email: sending emails that include a copy of itself as an attachment. The computer is infected when the attachment is run.

It is dropped or downloaded to the computer by other malware specimens, for example: Sdbot.HMW.
